SOLUTION: Megrez, the nearest of the Big Dipper stars, is 6.6 x 10^17m from the Earth. Approximately how long does it take light, traveling at 10^16m/year, to travel from Megrez to the Eart

Question 39863: Megrez, the nearest of the Big Dipper stars, is 6.6 x 10^17m from the Earth. Approximately how long does it take light, traveling at 10^16m/year, to travel from Megrez to the Earth?

This is another example of
Distance = rate x time or
D = RT
Since we are looking for time, we have
T = D/R
T = 6.6 x 10^17 / 10^16
T = 6.6 x 10
T = 66 years
hence Megrez is 66 light-years away from Earth...
